摘要

采用反应铸造法将钛颗粒混合形成Al3Ti金属间相，制备复合材料试样。干滑动摩擦试验采用45级钢固定套筒在旋转盘（试样）上端部加载的方案，滑动速度为0.25 ~ 0.75 m/s，载荷为0.5 ~ 3.5 MPa。构建磨损强度图，确定测试期间的摩擦状态。给出了改变摩擦状态的边界和条件。

Wear Conditions for a Composite Material Based on an AO20-1 Antifriction Alloy Reinforced with Titanium Particles

Composite material specimens are fabricated by reaction casting by mixing titanium particles to form Al₃Ti intermetallic phases. Dry sliding friction tests are carried out according to the scheme of end loading of a fixed sleeve (grade 45 steel) on a rotating disk (specimen) at sliding speeds of 0.25–0.75 m/s and loads of 0.5–3.5 MPa. Wear intensity maps, which determine friction regimes during a test, are constructed. The boundaries and conditions for changing the friction regimes are shown.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
